Sure thing.... I'll measure it this week and reply back to you.

Thanks
Thank you mate

I have to say I'm very impressed with the Conti's. A few have said that as the compound is softer than the Michelin PS4S's it will wear quicker - but I've not seen anything to be concerned about. I haven't been able to push these tyres in the bends to see where the grip limit is due to the weather and time of year, but everything I've thrown at them they have taken well.

I've always been a fan of the PS4S's and my 20" wheels will need a new set of tyres this year. I'm still leaning towards the Michelins but the Conti's do come in a few hundred pound cheaper so that might swing it (unless I find a 4 tyre discount code on black circles).

As for the 19" wheels, I think I'm starting to prefer the 19" over the 20"... driving seems more smoother and some what more enjoyable... maybe because I'm not constantly look out for potholes and worrying haha! I have hit a few potholes with these (in the dark on roads I'm not familiar with) and it's been okay... not as obvious as it is with 20" wheels and tyres.

I do prefer the look of 20" but practicality and for everyday use, 19" is the way forward I think.

The last few bits for the 'performance' project have arrived. As well as fitting the new turbo, downpipe and the other bits that go with that, I'm also changing out the coolant tanks to the newer versions, along with new coolant pipes and caps.

Leaking coolant tanks and split coolant pipes seems to be quite a common issue on the G30 platform. BMW is aware of the issues and released newer versions of all these parts. I haven't had any major issues but doing this as a preventative measure.

Looking forward to seeing what the newer Pure800 Cast turbo can do on pump fuel (99 RON) initially. I will then look what can be done with other fuelling at a later stage. I've seen some impressive results with this turbo, hence my choice. I was also considering the Turbosystems Stage2+ Turbo but went with the Pure one for a few reasons.

The car is booked in for all these bits to be installed. It will be done by my friend who is a local BMW Specialist. Just finalising who to get the custom tuning done with on BootMod3.

Parts to be Installed:
  • Pure Turbos Pure800 Cast Turbo
  • Pure Turbos Silicone Turbo Elbow
  • Osprey 5" Catted Downpipe
  • NGK 94201 Spark Plugs
  • BMW Turbo Gasket
  • BMW Downpipe Gasket
  • BMW Oil & Coolant O-rings
  • BMW Turbo Bolts
  • BMW V2 Coolant Tank
  • BMW V2 Charge Cooler Tank
  • BMW Coolant and Charger Cooler Tank Caps
  • BMW Coolant Tank to Radiator Pipe
  • BMW Intake Manifold to Charge Cooler Tank Pipe
  • (Oil Service to be done and Coolant to be changed out too)

Think you're spot on there, I've now got 2 flat spots in my 20's one front one rear due to a nasty pothole I encountered end of last week. My logic of wearing out the RFT Goodyears before adding non RFTyres clearly wasn't the best logical step! Think I'll see if they can be repaired and then try a set of Conti's in the 20", failing that some 19's all round.

There are (usually) ways to massage out a flat spot, if it's not too bad. Go see a wheel repair guy. You can even DIY it, if you're brave enough for such things. I've seen it done with a mallet and a board with a curve cut into the end of it.

LOL! I do feel your pain... quite early on in my ownership I hit a pothole at around 60mph and both passenger side wheels took a knock. The rear wasn't too bad but I had the front wheel heated and reshaped. It wasn't 100% again (it never will be) but it did the job for the time being.

that's always been the aim and goal - to build something a little different and to my taste, with inspiration from others in the BMW community.

Key Casing/Shell Replacement

Thought I'd share a very inexpensive change that I made to my car key... in essence, I bought a replacement key casing/shell for my main key and also the badge that goes onto it.

My main key is now over 5 years old and started to look a little warn. I was the 2nd owner on my car and the key wasn't in the best condition when I received it. Now it's at a stage where it's been dropped many times, the badge has worn off and the matt feel has worn off leaving a shiny surface to it all. I could have started to use my spare key but I want to keep that in it's new, unused condition (the next owner will thank me one day) ha 😄

I came across the replacement casing on AliExpress. Initially I thought for £3.33 it wouldn't be any good and probably wouldn't function as it should. To my surprise, the fitment and quality is really good. I weighed both keys before and after, both came in at 69g.

The replacement badges came as a set of 2, for £2.20 from the popular auction site.

I was able transfer the internals of the original key into the new case. Everything fits as it should and all buttons function as they should too. The only thing I didn't use from the new casing was the button membrane. The OEM seemed be of a better quality and fit. I also just used the manual key bottom piece from the original key.

£5.53 is what it all cost in total - which I'm quite pleased with!

Not to hog your build thread but this is the front... not too bad & hoping it will straighten. Downside theres a minor bulge in the tyre wall, hard to see but you can feel it, just.

This is the rear, doesnt look too bad head on but at an angle it seems to have pushed the rim out as well .. not so sure on this one. I'm taking the wifes wheels in for a general refurb on Monday so will find out then.

That's okay it's nice to talk on this thread rather then me just post my stuff

Oh wow! They should be able to heat it up and then they can be straightened out. Just goes to show how firm the runflats are and how soft the alloys are in comparrison. Is the bulge just before the E on the tyre?

What's your thoughts after sorting this... getting into a set of 19's with non runflats?

I suspect that bulge would go away once the dent is massaged out. This should be totally fixable a local wheel repair shop. Can't image it'd be more than a 100 bucks, or so, since there's no rash.

Thanks!

Well spotted bulge is just before the E.

I was hoping to be able to wear the run flats down and then replace them with non run flats on these wheels, as I like the wheels. Logic was that as the tyres are 245 & 275's although the profile is less than the orignial 255x35x19's I had on the previous F31's (which both came with rft), the actual tyre wall would be more and probably acceptable for a while. I now know that not to be the case

So first step is to try to get them repaired, according to my wheel guy it should be possible, but no guarantees and they will require a refurb as well due to the heating up and work to reshape. If that's sucessful I'll get him to refit the tyres and see how they are. Current thoughts are, if they are okay I will likely fit a set of non run flats to them and that will be my summer set.

I've always had a set of winters in the garage for my previous cars as our son lives in Germany and we go there quite often, especially in the winter, and if it ever does get bad over here I like the confidence of going anywhere without too much of a problem. So I would then as a second step get some 19" wheels, non run flats but may consider all seasons as long as they have the snow symbols.

In saying all that if they are not repairable I either have to splash out on 2 new wheels at around £1400 less a bit of discount, but in doing that wouldn't risk using RFT again so plus a set of tyres as well. If it's looking that way my other thought is just to get a set of 19's non RFT and enjoy those and wait and see if any good second hand 1001M alloys come up for sale. Unfortunately in the 'M Sport Edition' 5er which mine is, they only did 1000 of them and the 1001M wheels were bespoke to those cars, so could be a long wait? I'll see how the repair goes first.

Can I ask, do you have any size issuse with the Conti and the x-Drive allowable tollerences at the moment? I'm doing some research into rolling circumferences / diameters etc to see if non * tyres are within BMW limits, but not easy as manufacturers produce tyre in accordance with ETRTO ( European Tyre and Rim Technical Information) that has a +1.5% & -2.5% (mm) tolerence. So I trying to work backwards from spec info on Goodyear * RFT

Well would hope so but suspect that it may not as the wheel rim is now further away from the tyre so less pressure on it, but lets see.

To repair they are £156 (circa $198) each but that includes a refurb which is required. It seems that as they are diamond cut the heating process will discolour the existing finish and damage the lacquer and some marks are inevitable with the straightening process. At least they are on the same side of the car so will match each others in the event of the OEM match not being 100%

Hopefully they can repair them and then you can fit a set of non rft's to them. That will be the least hassle free option for you. £1400 for 2 wheels is steep and then there is the risk of it happening again. Always seems to be the common issues with OEM 20" wheels.

no size issues, I went with the standard 19" sizes they supply from factory. Even the wheels themselves are oem widths to mimise any issues. The tyres are not star marked but when I did my workings out, these were within 1% rolling diameter - think it was something like 0.52%.

I used this calculator to work it out:

That my friend is a brilliant calculator, thanks!

Think the biggest problem with OEM 20" is the runflats they put on them that causes most of the issues.

I did note on the forum that someone bought PS5's non * and the fronts were about 2cm smaller than the rears in standard sizes, so way off the mark, just didn't want to end up down that hole! Guess will just have to be careful in tyre choice, more performance orientated rubber will hopefully be to tighter tollerances?
